She disappears like bubbles; You enchanted her with just a shard of your smile
That's why, yes, she wanted to catch you, she ran in her dreams
But no matter if she reaches out her hand, it won't reaching
Such an empty tone of sound

She disappears like bubbles; You enchanted her with just a shard of your smile
That's why, yes, she wanted to catch you, she ran in her dreams
But no matter if she reaches out her hand, it won't reaching
Such an empty tone of sound
It echoes, the mermaid's tone of sound

Although "a mermaid's tone of sound" is awkward, is refers to the pitch that she makes. Just saying sound could be any sound, and this refers to singing.
